1,500 ~ 2,500 lbs is about the max you want to tow with a 2.3L. An automatic might be better, but expect a lot of down shifting. A manual transmission will be better suited for long distance and will run cooler. But getting a rolling start will be one problem, along with downshifts on hills.
I found that when hualing or towing @ 65mph, before you lose too much speed, down shift to 4th gear and hold 60mph when climbing gades. If you don't make the shift, loss of power will incure and a downshift to 3rd will be needed.
In the best set-up for a 2.3L, a 4.10 axle with stock size tires. Tranny of your choice (automatic if you are lazy, manual for better gear hold).
